Time is not enough for me

Everyone has 24 hours per day.Why my time is not enough for me to prepare myself in every subject?I understand why time is not enough for me.This is because i can't finish homework or assignment efficiently in a short period of time.What should i do to improve my studying skill?I really sad with my studying skill because i always can't finish my target and arrange my time wisely.Time passed very fast and i already have studied at kmph for half of a year.After four months later,i can leave kmph and continue to study in university.Sometimes,i have studied at hostel until i feel so boring.However,i know i just study at here for almost half a year,i need to continue my lesson in university for at least three years.How could i adapt myself in such a strange place and make friend with others?It is a challenge for me to achieve my target at kmph before i can study in university.My first semester result will come out soon and i know i need to ready myself to accept all of the possibility.My parents are waiting for me to tell them my result but i tell them first that don't be too coonfident in my result because i know my level.
